A lead for delivering electrical signals to and/or receive electrical
signals from a human heart that includes a solid inner conductor, and a
fixation device having a titanium nitride coated surface and electrically
coupled to the inner conductor. A steroid is applied to the titanium
nitride surface of the fixation device, and at least one layer of
insulation is positioned around the inner conductor. A conductive coil is
positioned around and is insulated from the inner conductor, an electrode
ring electrically coupled to the conductive coil is positioned around and
is electrically isolated from the inner conductor, and an insulating
spacer is positioned between and electrically isolates the ring electrode
and the fixation device.
